To all 'whom it 'may concern:

Be 1t known that I, FRANK A. Fox. n4

eitizen of the United Sintes, residing,` in New is n.,

York city, inthe county o' New York und i i specification. Thisinvention relates to anti-skid de'vires g for tires espeeinlly oi' thepneumatic typo, f and has for its object. to provide :in impr-awed formof trend for rho link in which on the oppositie sidesof the tread fecethere will form sharp 4edges for engaging; the ground.

A further object is to provide en upwardly projecting lngl extendingtransversely :ind

of the cross chains. Figs. Snnd -lshow the n l forming n trend portion,which 1s iornled hy l 1 ooimeeting link ni the ends ol' the eros-Hineinhers. Fig. 5 shows in perspective one ol' the links oi the crossmember. another forni ol' link. Fig'. 7 is'nrross ser. tion onizl'1o-.fii..'ie 7"-7 indicated in,4 Fifi'. Fig. n. se'etion on theline-vr? indiented in Fig. i) is n, section on the line -i indien'ied iniiig'. 5. Fin'. id shows the hhinh from whim the link oi" Figi. o irsi'orlned nnd Fig'. 1l shows the hlnnk Fig'. o.

The. present forni oi' link comprises essentinlly ori-isolatingpori-ioniy on the ends oi he. links hy which they :rre joined togiither,and havingon lhetwo transverse sides npwwrdly projectingd lugs/the endsoi' whieh i'orin treed portions. lhese lugs :ire preferably sul portalon their inner sides. Another essentiel featd're'is mi iiritlx'rned lngIextending,r tinnsversel') oi the link end transversely Ato the sind.inns, whiehlu formedhy bending upward the n'ietoriiii et the eyeopening; instead ol renoving sneh nniterinl to leave n clear opening.The .support for the two side lugs is preferably nn extension of the'iportion'of the link, thnt envnges the eye of the corresponding adjacentink.

In the consti-notion illustrated., the iink is provided with on eyeportion 12 at onel end, i

Fig'. i5 shows forjhe iink oi'l 'and hook portion 1'3 at the other end.0n 1 i portion, preferably having opposite sides are-.npturned ings 15und 16. The hook portion. las an extension Mfengaging the inner sides ofthe lugs at their top and thereby supports tliein from being: bentinward, and Iin con j onction with 'jiheir end portions iorin the trendportions for the link.

'l'he extension '14 has on integral supporting its extremity 17 bentdownward to engage the hase. ln forn'lirg` the eye portion 12, i:hennitffrin-l that .ronld be honi upward in the forni of n lunv i8; snehnmrerizil being severed ai three sides of the opening;- ith one sidejoining :it whiehfit is bent npnnrd. The top edge oi" the lng' 18 isflush -with the top edge of the" eidey hins'i and lo, ond. wih the trendportion 14 of the hook. lhe eye portion 12 is preferably given n.nlightnpwmd bend l'ronithe base so that the iinks'enn nil lie in thesaune plone when joined :n: indii-oted in Fig. 7. Andt'ne trend portionvI4 ol' 'he hook in loeided nhovetheplnne enganrenlent'- o i the hookportion with "the hook `pori-ion, whereby` he trend portion ezln neen'entireijf iin'ounjii.before the hook `vill disennrin'e (he eye. ily thisconsti-netion it n ill he seen that on hoth sides oi the. series oi"links' there is. n ,'-iinerp edge l'orined h v the, endo oi the tno.iside lugs, whereby -the trend portion of' the hooh is ntrongi;proieelf ed zri'ninet n'enr. Tuoro is nlsoihe ironsve-rse hin` 18hnving-im end portion engin the `Lronnd nnd prelim-ing ereinnreniertion.

` All the endo links are provided for engaging the' side rhnins 2() und2l, ihn( inn): oom'- priise :in 'eye pori-ion 222 engr-aging the hook l:1nd n hook port-ion ior menging ijhe side ehnin. The iinks nrenreiiernlz'iw' reverse on the two end portioin; oi the cross nienlherswhieh Ais done -hl'i' :i donhle hook nieniher shown sepnmt'e innig'. (3.ln his nrrmigrenient, the iinh has o' hook 24 of. one. end hmvm ing e'trend portion 255 `with the end 26 nent downwind to engnge the hose andsupport lr E 'the trend "pori/ion. The iink hns nisiniihir removed toform the openings, is

the said tread portion. The two hooks will engage the eyes of theadjacent links as shown in Fig. 7 thereby providing a hook across memberconsisting o'f a series of links portion at each side of the crossingmember for-connection with the side chain by -the said links. Thiscenter link has the same edge of side lugs with their ends engaging thegroundto prevent a sharp edge and provide a strong frictionand-engagement with the road.

Having thus described my invention, IA

claim:

1. In a device of the character described,

' a cross member consisting of a series of links articulated attheir-ends, the links having integral lugs projecting upwardly from thebase on each lateral side, and a tongue por-- 'tion extendinglongitudinally and engaging the lugs along 'their extremities.

2. In a device ofthe character described,

articulated at their ends, the links having integral lugs projectingupward from the base on each lateral side,l a tongue portion extendinglongitudinally and en' aging the lugs adjacent their extremities, ana'transversely extending lug bent upward fronrth'e base with its topforming a tread portion.

3. In a device of the character described, a cross member consisting ofa series of links having integral hook and eye portions by which theyare jointed, the hook portions of the links being extended along thelinkto vi'hich they are jointed, the hook portions of the links beingextended along the link to form a tread portion, an integral lug bentupy itard on each of the two transverse sides v. ith

its extremity engaging the side of the extended hook portion and forminga tread portion,and an integral portion supporting said tongueextension.

5. In a device of the character described,

i a cross member consisting of a series o f links having integral hookand eye portions by whichthey are jointed, the hook portions of thelinks being extended along the link to forma tread portion, an integrallug bent upward .on each of the two transverse sides with its extremityengaging the side of the extended hook portion and forming a treadportion, and a transverse lug portion 4bent upward from the eye openingand engaging the end portions of the side lugs to form a tread portion.

G. ln a device of the character described, a cross member consisting ofa. series of links having integral hook and eye portions b'y hieh theyare jointed, the hook portions ci' thelinks being extended along thelink lo form a tread portion, and an integral lug bent npward on each oithe tno transverse sidesl n ith its extremity engaging the side of theextended hook portion and forming a tread ortion, the extremity of thehook extension lieing bentdomiv. ard to engage the base and support thetread portion.

7. In a device of the character described, a crc-ss member consisting ofa series oi' links having integral hook and eye portions by lv hic-.hthey are jointed, the hook; portions oi' the links being extended alongthe link to form a tread portion, and an integral lug b'ent upii'ard oneach of the tto transverse sides v. ith its extremity engaging the sideotl the extended hook portion and forming a tread portion, the extremityof the hook extension beingbent dov. nr. ard to engage the base andsupport the tread portion, a transverse lug portion bent upv`l ard fromthe eye openin adjacent the said bent hook extension to torni a treadportion, anda link in the cross member having hook portions on tvvoopposite ends', n ith a lugbent upward on each transverse side engagingthe sides of the hook portions.

-8. In adevice of the character described, a cross member consisting ofa series of links having integral hook and eye portions by vhich theyare jointed, the hook portions olf the links being extended alongthelink to form a tread portion, and an integral lug bent upward on eachof the tv'io transverse sides with its extremity engaging the side of'the extended hook poition and forming a tread )ortion, the extremity ofthe hook extension oeing bent downward. to engage the base and supportthe treadportion, a transverse lug portion bent upv. ard from the eyeopening adjacent Jhe said bent hook extension to form a tread portion,and a link in the cross member having hook portions on tv. o oppositesides extended and having. their ends bent den nxrard in engagement 'nith the base, and a lug bent up ard on each transverse side inengagement n ith the said extension to form tread portions.
